Clear skies and a cool start greeted San Jose this morning, as Mineta San José International reported about 66°F while northwest winds were already picking up across the hills. A Wind Advisory remains in effect into late morning, and gusty conditions will make exposed ridgelines, passes, and some beaches especially blustery. Inland valleys are forecast to warm into the low to mid 80s this afternoon, so expect a combo of warm daytime highs and breezy commutes.

Afternoon Winds Pick Up Steam

According to the National Weather Service, northwest surface winds of 10 to 14 mph are likely across the valleys with gusts into the 20s, while favored gaps and ridgelines could see much stronger bursts, locally 45 to 55 mph. The Wind Advisory is expected to hold through about 11 AM today, and the gusts can make driving difficult for high-profile vehicles and knock around unsecured outdoor items. Secure patio furniture, provide extra space for cyclists and pedestrians, and allow more time for commutes on higher terrain.

Coastal And Boating Hazards

West-facing beaches and nearshore waters are under a Beach Hazards Statement and small-craft advisories into Monday morning, making shore breaks dangerous and seas choppy. Our overnight wind advisory rundown has additional background and safety tips for the overnight advisory, including staying off jetties and avoiding unnecessary boat trips. The combination of gusts and sea spray can also reduce visibility and complicate water-rescue efforts, so plan accordingly if you have ocean plans.

What To Expect This Week

Winds should ease later today, with inland highs rising into the upper 80s Tuesday and near 90 by midweek before onshore flow returns and coastal temperatures moderate. Low humidity in the interior will keep elevated fire weather concerns through Monday in brushy and higher terrain, so postpone spark-producing activities and report any smoke to authorities. Check updated forecasts and marine advisories if you have plans on the water or in exposed coastal areas later this morning and this week.
